Hopefully, someone in your area will help out with information on the Davidson. Doing a Google search I found DRO Outfitters located at 95 Pisgah Hwy, Pisgah Forrest, NC.Home
I noticed that they offer a newsletter, you might get on their site and sign up, also if they are close by I would recommend stopping in and letting them know you are a new fly fisherman and looking for information on the Davidson, public access points and what flies they recommend, and buy a few flies from them for their help.
